Gold-bearing gravel of nezperce national forest, Idaho county, Idaho
Clearwater Mountains have yielded nearly $50,000,000 in placer gold; outlook favorable, for large-scale operation of low-grade deposits; deposits of high-level and recent-valley type, latter ordinarily much smaller but richer; about 23 properties in Elk City, Tenmile, and Castle Creek districts are briefly described; Florence, Dixie and other districts in general area are not included in report.
